What is the purpose of this trial?

This trial tests a new therapy for individuals who struggle with arm or hand use after a stroke. It compares a brain-controlled robotic hand device, the IpsiHand Device, with regular at-home exercises. The goal is to determine if the robotic device improves hand and arm movement more effectively than standard exercises. This trial suits those who have experienced a stroke and currently face difficulty moving one arm or hand. As an unphased trial, it provides a unique opportunity to explore innovative technology that could enhance recovery.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are receiving Botox injections for the upper extremity, they must be timed to coincide within a week of the beginning of training.

What prior data suggests that the IpsiHand device is safe for use in stroke patients?

Research shows that the FDA has approved the IpsiHand device, confirming its safety in helping stroke patients regain movement skills. The device uses technology that connects the brain to a computer and has been tested on individuals who experienced a stroke some time ago. These individuals have used it to improve hand movement.

Earlier studies indicate that most people handle the IpsiHand well, with no major safety issues reported. Participants must follow instructions and use the device as directed to prevent any problems.

In simple terms, the IpsiHand device is considered safe for stroke patients, with no major issues found in previous tests. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional stroke rehabilitation methods that focus on physical therapy and exercises, the IpsiHand device is unique because it utilizes a brain-computer interface (BCI) to assist stroke patients in regaining hand movement. This device combines a robotic exoskeleton with EEG technology to interpret brain signals, allowing the exoskeleton to open and close the patient's hand. Researchers are excited about the IpsiHand because it directly engages the brain's neural pathways, potentially leading to more effective rehabilitation outcomes by harnessing the brain's natural ability to reorganize and recover after an injury. This innovative approach could offer new hope for stroke survivors who haven't seen significant improvements with conventional therapies.

What evidence suggests that the IpsiHand device is effective for stroke rehabilitation?

Research shows that the IpsiHand device, which participants in this trial may receive, can help stroke patients improve arm and hand movements. People with long-term stroke effects who used the IpsiHand experienced noticeable improvements, particularly in moving their arms and hands. Studies found that participants made real progress after just three months of using this brain-computer interface (BCI) therapy. The device enhances the brain's interaction with muscles, crucial for stroke recovery. This method offers promising results for those with arm and hand difficulties due to stroke. ^{2 3 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults aged 18-85 who have had a stroke and now experience weakness or paralysis in one arm. They should not be receiving other upper extremity therapies, have severe cognitive impairments, contractures that prevent device use, certain communication difficulties, or conditions affecting pain sensation.

Exclusion Criteria

I can feel pain and do not have nerve or sensory issues that affect this.

You have trouble understanding and following written instructions or have a low score on a language test.

Trial Overview

The study compares the effectiveness of a home-based brain-computer interface therapy using the IpsiHand System against standard exercises for improving arm function after stroke. Participants will either use the BCI-controlled robotic hand exoskeleton at home or follow an exercise program.

How Is the Trial Designed?

Group I: Standard of Care - Home Exercise Program for Upper Extremity Experimental Treatment 1 Intervention

Phase 1: Group 1 subjects will receive an IpsiHand Screening System to complete a remote EEG Screening. Once randomized, the participant will be assigned to group 2 to begin standard of care treatment at home. Phase 2: After being assigned to Group 2, subjects will serve as the control group in the study. Subjects will receive a customized home range of motion exercise program. Subjects will be recommended to complete their exercises daily, 5 out of 7 days per week for 12 weeks to control for the non-specific motor and sensory effects of BCI training. To help ensure compliance with the at-home portion of the protocol in the control group, participants will receive daily virtual monitoring from the study clinical specialist.

Group II: BCI treatment Group using the IpsiHand Experimental Treatment 1 Intervention

Phase 1: Group 1 subjects will receive an IpsiHand Screening System to complete a remote EEG Screening. Subjects will undergo an EEG screening protocol to ensure that a consistent control signal will be present to control the IpsiHand device. After an EEG screening session is complete, the participants screening data will be analyzed to ensure that sufficient cortical signals are present. Randomization for assignment to group 1 or 2 will then occur. Once assigned to group 1, if consistent signals are found, the participant will then continue to Phase 2. Phase 2: Group 1 subjects will be provided with a Neurolutions IpsiHand BCI system, which combines a novel powered exoskeleton with a commercial EEG amplifier and active electrode system. The exoskeleton opens and closes the patient's hand in a three-finger pinch grip. Patients will use the BCI system on a minimum of 5 days per week for 12 weeks. Patients will complete five or more 10-minute runs of the BCI task per day.
